What Reaction Occurs When Hydrochloric Acid and Zinc Are

When hydrochloric acid and zinc are coined, they create hydrogen gas and zinc chloride, which is a salt. A small piece of zinc metal is then added to the hydrochloric acid. When the zinc is introduced to the hydrochloric acid, it rapidly bubbles and produces hydrogen gas. The hydrogen gas that zinc and hydrochloric acid produce has

EXTRACTION OF METALS

The most reactive metals are extracted from the sea. Calcium is extracted from limestone, chalk and marble in the sea. Metals of medium reactivity are found in the earth in form of oxides and sulphides. Examples of these metals include aluminium, zinc, iron and tin. Least reactive metals such as silver and gold occur as free uncoined elements.
